Goal

• Goal: Isolate the variable (get the variable on one side by itself)

  
  

• You must keep both sides balanced by doing the same thing to both sides.

Line

We use the red line to remind us that we do the the same thing to both sides.

Multiple Choice

x - 5 = 5

What are we trying to do?

• Get the 5 by itself

• Get the x by itself

Multiple Choice

x - 5 = 5

What do we do first?

• add 5

• subtract 5

Multiple Choice

x - 5 = 5

What side of the = do we add the 5 to?

• the side with the x

• the side without the x

• both sides

Multiple Choice

Multiple Choice

What are we trying to do? What is our goal?

• Isolate the + (get the + by itself)

• Isolate the y (get the y by itself)

• Isolate the = (get the = by itself)

Multiple Choice

What do we do first?

• Subtract 5 from both sides

• Add 5 to both sides

• Subtract 20 from both sides

• Subtract 20 from one side and 5 from the other side.
